I think the OP asks a great question & I'm not sure I know the answer. Some real good suggestions have already been posted.
If you want my 2 cents, I can't see why you are not getting it closer to the hole. YOu have outstanding equipment and I think maybe trying to get better at getting the ball closer to the hole will really help of course & that's just a matter of practice.
Personally, I own every putter for my level & I'm kind of ashamed to admit it, but I can only drain these hard Oakmont putts,for instance, with a level 19 Spider. lol
It has a real slow meter for feeble old farts like me & allows me to hit these short sharp breaking putts with more force & confidence.
It's not a solution for me to keep using this level19 Spider. I am trying to get used to the Daytona Rossa. I can't stand that Nike you are useing idk.
But I am not the putter that like to ding too many putts, I like to work this putter(hit it off the toe or heel).
Someone suggested using the higher scale on the putter for shorter putt & hit them firmer & I think that's a good suggestion.
Just some thoughts.
Hope you get to knockin it in soon.
